MIXING VESSEL.

1 Specification of Letters Patent.

Application filed January 31, 19h. Serial No. 605,756.

.To all whom it may concern "and State of New York, have invented a newvand Improved Mixing Vessel, of which the following is a'specification.

'1 hot material within.

' .tion-s, a, a, i orme'd, in the present case by My invention relatesgenerally to vessels employed in mixing materials of a liquid nature,more particularly those by the ad-,

mixture of which chemical reactions are effected, byw'hich reactionsheat is developed or for the eiiecting of which heat is required.

As is well known in the mixing of many substances to form new compounds,a considerable degree of heat is developed, insome cases to such anextent that precautions have to be taken to prevent overheating, withundesirable or'dangerous consequences.

Heretofore such overheating-- has been pro:

vented by mixing the chemicals ina cylin drical vessel surrounded by awater jacket and by'limiting the quantity of combining materials so thatthe amount of heat developed should be inconsiderable.

The object of my improvements isto pro vide a mixing vessel of suchconstruction that the heat generated shall be more efli' cientlyremovedthan heretofore, to the endof a more rapid admixture of materialsand -m1x1ng vessel, instead of following directly 'in greater quantitythen has been possible. This I accomplish by giving to the wall of themixing vessel such a shape or configuration that all portions of thematerial within the vessel are quickly and successively brought incontact therewith and impart their heat thereto as they are moved aboutby the mixer while at the-same time the cooling Water on the outside ofthe mixing vessel is brought into contaot with the -wall thereofinZp'uch manner as to more elliciently remove heat imparted thereto bythe illustrating an embodiment thereof, Figure 1 of which shows avertical section of the mixing vessel and Fig. 2 shows a horizontalsectionof the same on the line 22,1Fig. 1.

Referring to the drawings A indicates the mixing vessel, the wall ofwhich is provided, within. and without, with vertical projecinaking thewall with a corrugated section, as shown.

B -indicates an outer wall surrounding the mixing vesselA, theinterposed space formmg a water acket-into which a stream 'of PatentedAug. 26,1912.

water is admitted through pipe I), which is preferably set tangential tothe wall of the mixing vessel.

through plpe b.

Within the mixing vessel A, is a rotary stirrer, C, mounted on a shaft,0, of any usual or convenient construction. The vesof the vessel andpartly remaining at the center, as is the tendency in. ,the case lofsmooth walled vessels, is broken/"up into cur rents, by striking againstthe ribs a, a, which are turned toward the center of the vessel,

,somewhatasindicated by the arrows Fig.

2, so that a quick andthorough mixing'fof the, mass is effected andall'its parts are successively brought against the wall of the mixingvessel and are cooled by contact therewith. In the same manner thestream of The admitted water escapes :from the upper part of the waterjacket, as

water admitted to the-water jacket throu h pipe 6, and impingingon thewall oft e around the wall, is broken up by contact with the ribs'orprojections so that the outer and cooler portions of the water arecontinually brought into contact with-the wall and remove the heattransmitted therethrou h.

It will be understood that the vertica ribs or extensions by means of,which the desired movement is given to the-liquidsimay be in.

various forms, which will readily occur to those skilled in the art, andI do not limit my invention to the use of the particular form shown,though I have found this efiicient and desirable. It willbe evidentalsothat my invention can be used with equal advantage in cases where heatis' not developed by the reactions in the mixing vessel and where it isdesired to transmit heat from the water jacket to the mixing vessel-topromote the reactions therein.

What I claim as new and desire to secure by Letters Patent is: .4 v

Ina mixing vessel the combination'ofa vessel wall having, withinandwithout, vertical corrugations, a horizontally rotating stirrerWithin the 'vesseL'e water jacket sur-" subscribed my rounding thevessel and an inlet pipe to said Water jacket tangential to the vesselWall, whereby the liquld. Within end-Without the vessel is caused tomove intermittent-1y away from the-Wall thereof.

In testimony whereof, I have hereunto name, this 17th day of Janw ary A.D., 1911.
